Patented Mar. 18, 1941 UNITED STATEE PATENT OFFICE VJINDOW SCREEN CATCHThis invention relates to a catch or look and more particularly to aswinging catch for holding a screen in a window casing.

An object of the invention is to provide a pair of catches which willefiiciently hold a window screen in a window casing.

A further object of the invention is to provide a catch which will holda window screen in a window casing and permit the window to be openedand closed.

A still further object of the present invention is the provision of aswinging catch which is simple in operation and cheap to manufacture.

With the foregoing and other objects in View which will appear as .thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed without departing from the spirit of theinvention.

In the accompanying drawing- Figure 1 is an elevational view of theinside of a window screen in a window casing, showing my novel catchesholding the screen in place in the window casing.

Figure 2 is an enlarged horizontal sectional view of my novel catch on ascreen and the catch being in closed or locked position in a windowcasing.

Figure 3 is a perspective view of a portion of r my novel catch.

Referring in detailto the drawing, It is a window screen, comprisingwire netting l2 and frame-work M. The frame-work M on the two verticalmembers has a flange or extension portion It. The sides or the windowcasing are indicated by the numeral [8. Catches 20 are secured on theinside of the screen II] on the opposite vertical members of theframe-work M.

The catch 20 consists of a handle 22 having a tongue portion 24. A boltportion 26 comprises an angular extension portion 28. The bolt 26 isbifurcated at 30 and the tongue 24 of the handle 22 is pivotally mountedby a pin 32 to the bifurcated portion 30 of the bolt. The bolt has apointed inner end 34 which is adapted to be driven into the frame-work Mof the screen. An escutcheon plate 36 issecured by screws 38 on thevertical. members of the frame-work IA of the screen It). The catch 20is adapted to be inserted through an aperture 40 in its accom- Hazleton,Pa.

panying plate 35 so that the pointed end 34 is buried in the frame-workH of the screen.

As shown in Figure 1, the catches 20 are shown in locked position withthe screen It) held in place in the window casing. The angular portions28 of the catches 20 when in the position as shown in Figures 1 and 2abut the inn-er face of the casing members l8, and with the flangeportions l6 of the vertical members of the framework M of the screenabutting the outer face 10 of the members I8 of the window casing, thescreen H] is held in the window casing. The catches 2e are secured tothe inside of the screen, so that the screen can be secured in placefrom the inside of the window casing.

To operate the catches for removing the screen as shown in Figure I,raise the handles 22 of the swinging catches- 2!] so that they areperpendicular or at right-angles to the window casing portions l8. Thenturn or twist the handle 22 of the catch 20 mounted on the right side ofthe screen in a counter-clockwise movement, and then twist the handle 22of the catch 2c mounted on the left side of the screen in a clockwisemovement. Now both of the angular extensions 28 of the catches 20 havebeen moved from behind the window casing members [8, and the screen canthen be easily removed. When it is desired that the screen be placed inthe window casing, the angular extensions 28 of the catches 2!] are setso that they lie behind the frame-work M of the screen. Next, theflanges N5 of the vertical members of the frame-work Id of the screenmare made to abut against the outside of the members l8 of the windowcasing. The handle 22 of the catch 20 mounted on the right side of thescreen is twisted in a clockwise movement until the extension 28 of thesaid catch moves to abut the inside of the casing member i8. Then thehandle 22 of the catch 20 mounted on the left side of the screen istwisted in a countier-clockwise movement until its angular extension 28abuts the inside of the member ll! of the window casing. Now the screenIt] is secured in the window casing. The handles 22 of the catches 20are pulled down to lie flat against the frame-work M of the screen.

Various changes in the form, shape and other minor details ofconstruction may be made without departing from the principle or spiritof my invention comprehended within the scope of the appended claims.

Having described my invention what I claim as new and desire to secureby Letters Patent is:

1. In combination with a window screen com- 55 prising a frame, of alock comprising a bolt member, a lateral extension, and the inner end ofthe lateral extension having a driving point, the driving point of thelock adapted to be driven into the frame of the screen, a plate membersecured to the frame of the Window screen and overlying the innerportion of the lateral extension of the lock so as to hold the lock onthe frame of the window screen.

2. In combination with a window screen comprising a frame, of a lockcomprising a bolt member, a portion extending to one side of the boltmember, a driving point projecting from one side of the said extendingportion, the driving point of the lock driven into the frame of thewindow screen, a plate member secured to the frame of the window screenand overlying the inner portion of the said extending portion of thebolt so as to hold the lock on the frame of the Window screen.
